Upon diagnosis of DCM, the first thing most individuals are going to do is hit the Internet to do research. One of the first things they are going to discover is the Framingham study. This study states that 50% of people with DCM are going to die within 5 years of diagnosis.
This study is very dated. It does not take into account medical advances of treatment of DCM and heart failure. There are thousands of people that have beat this oft repeated statistic. When you read it, don't panic. Talk to your cardiologist. He should be able to tell you the latest information.
In addition, when you are home and alone and freaking over your 5 year death sentence, visit http://www.cardiomyopathy.org/ to read the accounts of all of the people that have made it past that 5 years. It will make you feel a lot better!
